  Selection of Current transformer for accurate measurement and reliable protection scheme     Selection of Current transformer     In Power system it is necessary to measure current but it is not feasible to measure current directly with measuring devise as higher current can damage the measuring devise or relay. So Current transformer is required that reduce current in measuring circuit (secondary) proportional to flowing current. Current transformer isused for metering and protection purpose. Selection of CTs In industrial Applications should be done properly for accurate measurement and reliable protection scheme so selection of CT plays significant role for metering and designing protection system. Various factors need to consider while selecting current transformer.   CT ratio is defined as ratio of primary and secondary current of CT. In order to defineprimary current of CT, consider subsequent rating of current to be measured or it should be selected from rating of
